What Are You Looking At?

Some day computers and apps will be able to monitor what you are looking at by watching your eyes. This eye tracking technology is in it’s infancy at the time I am writing this blog.  It  has not yet permeated our society.

At the moment, much of the focus has been on tracking the eyes of one person at a time. Eventually, it may be possible to track the eye movements of a room full of people simultaneously. They would not all need to be facing the same direction or wearing special glasses. Omni directional cameras could be strategically placed to see all eyes everywhere.

This could help architects and designers better understand how people perceive their environments. It could also help advertisers know when their ads have been seen. In a venue like a sporting event, it would be extremely valuable to know if the the most valued ad realestate lived up to it’s price.

Did You See My Ad?

“Did  you see my ad and for how long did you look? Did you just look or did your eyes read the text?” Advertisers want to know the answer.

When dealing with one person, It might be possible to project an image in such a way that no matter where that person looks, they see the projection. Eye tracking technology could determine where you are looking, and a moveable projector could create the display.

A Li-Fi Universe

I recently watched a Ted Talk by Harald Hass. He demonstrated the technology of Li-Fi (Light Fidelity). In short, it is the use of the visible light part of the electromagnetic spectrum to transmit data. Technology such as Wi-Fi uses the radio wave part of the electromagnetic spectrum. Li-Fi has a far, far greater data capacity than Wi-Fi.

In a way, astronomy utilizes a type of “Light Communication” already. Stars communicate their composition by emitting a certain spectrum of light. Astronomers then decode the light to determine what elements are present.

Some theorize that light travels at different speeds when in different mediums and perhaps in interstellar space. What if the speed of light moves a great deal faster between star systems?

Stars could communicate, or be a part of a communication network, in Li-Fi. Not to mention that stars also emit radio waves (Wi-Fi), ultraviolet waves etc. Quite a large spectrum.

Spiral Galaxy

Billions of stars buzzing with electromagnetic emissions.

And to go further out on a limb; what if stars are the equivalent of neurons or have the capacity for thought themselves? If the thoughts of these thinking beings move slower, at a different time rate than ours…. the time spans that it takes to receive information from star to star, may not seem long.
